If it's a spreadsheet, write the following formula, for example, in C1:
= A1 + B1
Or better yet, type "=", click on the first cell you want to add, type "+", and click on the second cell you want to add. The advantage of this method is that you are less likely to get it wrong.
Since the cells are adjacent, you can also use the sum() function. For example, in cell C1:
= sum(A1:B1)

If a is to the south of B and C is to East of B in what direction is A with respect to C?
A is to the southwest of C. The deviation from due south or west depends on the relative values of the distances from A to B and from B to C.
In the given ratio b and c are mean values?
true
How do you add fractions that don't have the same denominator?
if you are adding a/b + c/d the answer is (a * d + c * b)/(b*d)
Rules for matrix multiplication?
Suppose A is a pxq matrix and B is an rxs matrix.Then C = AxBis defined only if q = r: that is the number of columns in A is the same as the number of rows in B. The result is then a pxs matrix.Suppose the element in the wth row and xth column of A is awx.Similarly, let the element in the yth row and zth column of B is byz.Then the element in the ith row and jth column of C isai1b1j + ai2b2j + ... + aiqbqj where i = 1, 2, ..., p and j = 1, 2, ..., q.There are further rules for matrix multiplication.It is not commutative: in fact B*A may not even exist.It is associative. Provided they exist, A*(B*C) = (A*B)*CIt is distributive over addition: Provided they exist, A*(B+C) = A*B + A*Cand (B*C)*D = B*C + B*D.
A varies jointly as b and c One set of values is a equals 2.4 b equals 0.6 and c equals 0.8 Find a when b equals 0.4 and c equals 0.4?
a = 0.8
